Product Description
PC-3™
Smooth-On PC-3™ Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.
EZ-Spray™ Foam
EZ~Spray™ Foam is a polyurethane foam compound that can be conveniently sprayed using Smooth-On’s EZ~Spray™ Junior System. Foam cures quickly to strong, lightweight and impact resistant 8 lb. rigid foam that can be used for a variety of applications including making lightweight castings. Foam can also be sprayed over certain rubber mold configurations as a mother mold material. For more information, refer to SmoothOn’s EZ~Spray™ Junior manual and video.
